[0022] As Figures 1 to 4 shown, an automatic irrigation device for greenhouse seedling cultivation according to the present utility model includes a cultivation box 1. The cultivation box 1 is divided into a cultivation cavity 3 and a water collection cavity by a partition board 2. The partition board 2 is arranged as an inclined surface. The two partition boards 2 are fixedly connected by a filter plate 7. Soil is arranged in the cultivation cavity 3, and a seedling cultivation body is arranged in the soil. A water pump 4 is arranged on one side of the cultivation box 1. A number of partitioned basins 6 are fixedly connected in the cultivation cavity 3. Each seedling cultivation body is respectively arranged in the partitioned basin 6. The inner wall of the partitioned basin 6 is arranged as an inclined shape. By arranging the inclined partitioned basin 6, when the irrigated water seeps into the soil, it can be guided, and the water flow is guided to the root part of the seedling cultivation body, increasing the root absorption area of the seedling cultivation body, ensuring the full absorption of water at its root position, being beneficial to the growth of the seedling cultivation body, and improving the irrigation effect. A water tank 8 is arranged on one side of the cultivation box 1. The water inlet end of the water pump 4 is fixedly connected with a water inlet pipe, and the water inlet pipe is respectively fixedly connected in the water tank 8 and the water collection cavity.

[0023] In an embodiment of the present utility model, a spraying assembly 5 is arranged at the water delivery end of the water pump 4;

[0024] The spraying assembly 5 includes a water pipe 501. The surface of the water pipe 501 is arranged on the upper end surface of the cultivation box 1 at the same time. A number of inclined nozzles 502 and a number of rotating nozzles 503 are arranged on the lower end surface of the water pipe 501. The rotating nozzle 503 is fixedly connected with the water pipe 501 through a telescopic pipe. A connecting plate 504 is fixedly connected to the surface of each rotating nozzle 503. One end of the connecting plate 504 is fixedly connected with a rotating rod 505. The upper end surface of the cultivation box 1 is fixedly connected with a fixed plate 506. The rotating rod 505 is rotatably connected to the surface of the fixed plate 506 on one side. A limiting groove is opened in the rotating rod 505. The other side of the fixed plate 506 is fixedly connected with a motor 507. The output end of the motor 507 penetrates the inner wall of the fixed plate 506 and is fixedly connected with a limiting rod 508. The surface of the limiting rod 508 is slidably connected in the limiting groove at the same time. By arranging the spraying assembly 5, when irrigating the seedling cultivation body, the motor 507 can be driven to drive the limiting rod 508 to rotate, so as to drive the rotating rod 505 and the rotating nozzle 503 to swing left and right on one side of the seedling cultivation body, enabling the rotating nozzle 503 to ensure that the surface and root of the seedling cultivation body are fully irrigated, thereby reducing the evaporation of water and improving the irrigation efficiency.

[0025] Working principle: This embodiment provides an automatic irrigation device for greenhouse seedling raising. When in use, through the operation of the water pump 4, the water in the water tank 8 is transported into the water pipe 501, and the seedling raising body is irrigated through the inclined nozzle 502 and the rotating nozzle 503 respectively. By using the inclination of the inclined nozzle 502, the water can be accurately sprayed on the root position of the seedling raising body for infiltration. By using the connection between the rotating nozzle 503 and the connecting plate 504, at this time, the motor 507 is started to drive the limiting rod 508 to rotate in the limiting groove, so as to drive the rotating rod 505 to swing left and right, enabling the rotating nozzle 503 to swing left and right on the side opposite to the two sides of the seedling raising body, so as to irrigate the surface leaves and rhizome positions of the seedling raising body in all directions. After the watering is completed, the inclined surface of the partition basin 6 is used to limit the position of the watering water, so that the water can flow to the rhizome position of the seedling raising body for sufficient watering. For the excessive water, the inclined surface of the partition plate 2 is used to guide it to the filter plate 7 for filtration. The filtered water then enters the water collecting cavity for collection. When watering next time, the water pump 4 is started to transport the filtered water in the water collecting cavity for secondary irrigation.
